One thing I've found helpful is using my ripper point to lightly score along the stitch lines. Makes it easy to fold on the line for trimming seams to 1/4" and aids in easier tearing when it's time to remove the paper bits. Some folks say to shorten stitch length so the perforations are closer together and paper will tear away easier. I don't simply because when I make a mistake ( like sewing the fabric in wrong way out) the short stitches are hard to take out. I love paper piecing, too!! It's the only way I'll make flying geese!
